Description

[Detailed description of the invention] (Technical field) This invention relates to an air outlet device for a vehicle, and in particular has a barrel equipped with an air outlet inside a housing, and the rotation of the barrel causes the air to be blown out. This invention relates to an air outlet device in which the direction of air can be changed.

(Prior technology) As an air outlet device that blows air into the vehicle interior.
(a) A housing that opens into the vehicle interior; (b) A cylindrical housing that is rotatably mounted around the first axis within the opening of the housing and includes an air outlet for blowing air into the vehicle interior. a barrel, and (c) a plurality of parts disposed inside the barrel so as to rotate together with the barrel about the first axis and to be able to rotate relative to the barrel about a second axis. A type of air blower is known in which the direction of the blown air is changed by changing the direction of the blades and the barrel.

(Problem to be solved by the invention) This type of air outlet device has conventionally been installed in relatively low-grade vehicles, but in such an air outlet device, the blades are automatically oscillated. This has made it difficult to continuously change the direction of the blown air. Since the blades are designed to rotate together with the barrel, changing the rotation angle of the barrel will also change the position of the blades, making it difficult to transmit the driving force from the drive mechanism to these blades. This is because it becomes difficult.

(Means for solving the problems) The present invention was made to solve the above problems, and its gist is as follows:
The air outlet device includes (a) an interlocking member connected to the plurality of wind direction plates and rotating the wind direction plates in conjunction with each other, and (b) reciprocating in a direction substantially perpendicular to the second axis. (c) at least one of the wind direction plates and the reciprocation member in a state where the wind direction plate can rotate about the second axis and together with the barrel about the first axis; and a connecting mechanism that is rotatably connected to the reciprocating member and transmits a driving force from the reciprocating member to the at least one wind direction plate to cause it to swing.

(Functions and Effects) In such an air outlet device, when the barrel is rotated around the first axis, at least one wind direction plate (blade) is connected to the reciprocating member via the connection mechanism. It is kept in the same condition. Therefore, if the reciprocating member is reciprocated in this state,
The at least one blade is rotated about a second axis. The rotational motion is transmitted to all the blades via the interlocking member, and these blades are caused to oscillate in unison.

Therefore, with the device of the present invention, it is possible to swing a plurality of blades all at once while the barrel is positioned at any rotational position. Even in the barrel-type blowout device that was used, it became possible to continuously and automatically change the direction of the blowing air.

(Example) Next, an example of the present invention will be described in detail based on the drawings.

In FIGS. 1 and 2, reference numeral 10 denotes a housing of an air outlet device, which has an opening 12 at the front thereof. Inside the opening of the housing 10, a barrel 16 having an air outlet 14 is arranged so as to be rotatable around the axis (first axis) of a shaft 18. As shown in FIG. 2, this barrel 16 also has fitting parts 20 at the upper and lower parts, and the arc-shaped convex surfaces 21 of these fitting parts can slide on an arc-shaped concave surface (not shown) formed on the housing 10. is mated to.

Inside the opening of the barrel 16, a plurality of horizontal wind direction plates (horizontal blades) 22 are arranged vertically and fixed in position, and inside the rear thereof, a plurality of vertical wind direction plates (vertical blades) 24 are arranged horizontally. They are arranged in a row. The vertical blade 24 is rotatable around the axis (second axis) of a shaft 26 that is perpendicular to the first axis. In other words, this device:
By changing the direction of the barrel 16 and the direction of the vertical blades 24, the direction of the air blown out from the air outlet 14 of the barrel 16 can be changed vertically and horizontally. In addition,
The plurality of vertical blades 24 are connected to each other by an interlocking plate 28, so that the plurality of vertical blades 24 are interlocked and rotated all at once. Moreover, among these plurality of vertical blades 24,
The center blade is provided with a rod portion 30 parallel to the axis 26 at its rear portion, that is, its axis is located on a plane including the axis 26.

On the other hand, a reciprocating plate 32 that extends through the side wall of the housing 10 is arranged behind the plurality of vertical blades 24 . This reciprocating plate 32 is connected to a predetermined drive mechanism (not shown), and is configured to reciprocate in the left-right direction in FIG. 1 by this drive mechanism. A U-shaped piece 36 as an engaging member is attached to the reciprocating plate 32 at a portion located inside the housing 10 via a clutch 34. An engagement groove 38 extending perpendicularly to the first axis and the second axis is formed in the U-shaped piece 36, and the rod portion 30 of the center blade 24 enters into this engagement groove 38. There is. The diameter of the rod portion 30 is approximately the same as the groove width of the engagement groove 38,
When the U-shaped piece 36 is moved in the left-right direction together with the reciprocating member 32, the rod portion 30 moves into the engagement groove 38.
It is designed so that it can be moved together while rotating relative to it. That is, the center blade 24
can be rotated around the axis of the shaft 26.

The clutch 34 is for moving the U-shaped piece 36 and the reciprocating plate 32 relative to each other when a force of a certain magnitude or more is applied between them. Spring 40 pressing it against reciprocating plate 32 under force
(See Figure 3).

In such a device, the reciprocating plate 3
2 is reciprocated in the vertical direction in FIG. 3 (the horizontal direction in FIG. 1) by a drive mechanism (not shown), the driving force is transmitted to the U-shaped piece 36 via the clutch 34, and this U-shaped piece 36 They are moved back and forth together. Then, since the rod portion 30 engaged with the engagement groove 38 of the U-shaped piece 36 is moved together, the center blade 24 is caused to swing around the axis of the shaft 26. Since this center blade 24 is connected to other vertical blades 24 via an interlocking plate 28, when the center blade 24 is rotated, the other vertical blades 24 are rotated in conjunction, and the barrel 16 The direction of the air blown out from the air outlet 14 is continuously changed in the left-right direction in FIG. 1 (up-down direction in FIG. 3).

Note that the direction of these vertical blades 24 can also be changed by manual operation. Reciprocating plate 3
2 is stationary, and when a rotation operating force is applied to the vertical blade 24, the clutch 34 slides on the reciprocating plate 32, and only the vertical blade 24 rotates independently of the reciprocating plate 32. is allowed.

On the other hand, the barrel 16 can also be turned up and down by manual operation. That is, when a rotation operating force is applied to the barrel 16 in the vertical direction in FIG. 1, that is, in the clockwise and counterclockwise directions in FIG.
The barrel 16 is rotated about the axis 18 while the convex surface 21 of the fitting portion 20 slides against the concave surface of the housing 10. At this time, the U-shaped piece 36 attached to the reciprocating plate 32 is
Although in a stationary state, the engagement groove 38 extends in a direction perpendicular to the rotation axis of the barrel 16, so the rod portion 30 of the center blade 24 can freely move relative to each other within the engagement groove 38. Can be rotated. Therefore, the center blade 24 can freely rotate together with the barrel 16 around the first axis. Moreover, after the center blade 24 rotates, the rod portion 30 remains engaged with the engagement groove 38, so when the reciprocating blade 32 is reciprocated, the driving force is transmitted to the center blade 24. As a result, the plurality of vertical blades 24 are caused to oscillate in unison. That is, in this device, it is possible to swing the vertical blade 24 inside the barrel 16 while rotating the barrel 16 at an arbitrary angle.
This makes it possible to freely and continuously change the direction of the air blown out from the air outlet 14.

Although one embodiment of the present invention has been described in detail above, the present invention can also be implemented in other embodiments.

For example, in the above example, the engagement groove 38 and the rod portion 30 are located on opposite sides, that is, the engagement groove 38
It is also possible to provide the rod portion 30 on the side of the vertical blade 24 and the rod portion 30 on the side of the reciprocating plate 32. Further, in the above example, the engagement groove 38 of the U-shaped piece 36 is opened in order to insert the rod portion 30 of the blade 24, but such an opening is not necessarily required in the engagement groove 38. It is also possible to form the engagement groove in a closed form.

In addition, it is possible to make the shape of the rod part 30 such that its own axis is curved within a plane including the second axis, etc., and the present invention is based on the knowledge of those skilled in the art without departing from the spirit of the invention. It is possible to implement various modifications based on the above.
